ST-9980A+ Pro
DC EV Charger Comprehensive Tester
Portable GB/T DC charger tester with dual sockets, 1000 V / 250 A coverage, protocol analysis, short-circuit pre-check and IP67 field protection.

Product Overview
DC EV Charger Comprehensive Tester
ST-9980A+ Pro is a portable third-party DC EV charger tester with interoperability test support. It is designed for charger manufacturers, utilities, third-party inspection organizations, buyers and service teams carrying out R&D debugging, factory tests, field inspection and acceptance. It simulates the vehicle charging process, exports and parses charger messages, and adds short-circuit pre-checks for safer field operation.
Choose ST-9980A+ Pro for GB/T DC charger development, factory acceptance and field commissioning. It simulates the vehicle charging sequence and captures charger messages. The dual sockets are rated for DC 1000 V / 250 A; sustained power tests require a separate compatible load. Confirm optional protocol, interoperability and metering modules against your test plan.
Choose the right test configuration
Interface and workflow
GB/T DC charger development, factory acceptance and field commissioning with dual 1000 V / 250 A sockets. Confirm the required GB/T protocol revision and optional test modules.
External load and connection limits
No built-in load; external load connection up to 250 A. Specify compatible load voltage, power, cooling, cables and controls separately.
Options and accessories
Confirm optional protocol conformance, interoperability, metering, waveform, GPS, environmental and removable-battery modules. IP67 applies to the closed case.
Procurement checklist
Confirm the delivered configuration before ordering
Interface and standards
Confirm the connector, market, protocol and exact standard editions required by the charger and test plan.
Electrical and load path
Separate socket, cable and measurement ratings from the source or external load used during sustained power tests.
Evidence and options
List required metering accuracy, message or waveform capture, fault cases, report fields and optional modules.
Acceptance and support
Agree supplied accessories, software, factory acceptance checks, commissioning, training and support boundaries.
Key Features
Designed for reliable EV charger validation.
- 01Uses a GB-standard DC EV charging socket and supports current GB/T 2023-2025 standards, with optional protocol conformance, interoperability and metering modules.
- 02Vehicle-control-pilot simulation reproduces the charging process. Manual controls switch PE, DC+/DC-, CC1/CC2, S+/S-, S2/S3 and other charger signals for fault diagnosis.
- 03The tester exports and parses charger messages for operating-state analysis and abnormal-fault diagnosis. A short-circuit pre-check runs before charging to identify wiring risks.
- 04One-key start and stop, an Android operating platform, and PC software provide a direct workflow for test setup, execution and maintenance.
- 05The mobile trolley case is waterproof, pressure-resistant, shock-resistant and corrosion-resistant, with an IP67 closed-state protection rating for complex outdoor environments.
- 06Optional waveform, metering, GPS, temperature/humidity, timing and removable-battery modules extend the tester for interoperability and field verification work.

Product FAQ
Common questions about ST-9980A+ Pro
Is ST-9980A+ Pro a CCS2 or CHAdeMO tester?
This model uses GB/T DC charging sockets. For CCS2, compare ST-9980EA-HPC; for CHAdeMO, compare ST-6680CA-DC. Confirm the connector and protocol before ordering.
Does the 1000 V / 250 A rating include a built-in load?
No. These are socket ratings. The tester has no built-in power load and supports an external load up to 250 A. Load voltage, power, cooling and controls must be specified separately.
Which functions require configuration review?
Protocol conformance, interoperability and metering modules are optional. Waveform, GPS, environmental measurement and battery options should also be confirmed in the quotation. The IP67 rating applies to the closed case.
